Résumé: We analyze the statistical properties of the coverage of a one-dimensional path induced by a twodimensional nonhomogeneous random sensor network. Sensor locations form a nonhomogeneous Poisson process and sensing area for the sensors are circles of random independent and identically distributed radii.We first characterize the coverage of a straight-line path by the nonhomogeneous one-dimensional Boolean model. We then obtain an equivalent Mt/Gt /?‡ queue whose busy period statistics is the same as the coverage statistics of the line. We obtain k-coverage statistics for an arbitrary point and a segment on the x-axis.We provide upper and lower bounds on the probability of complete k-coverage of a segment.We illustrate all our results for the case of the sensor deployment having a ?gLaplacian?h intensity function.
